Can plants really purify the air in your home?

Houseplants are experiencing a surge in popularity — and for good reason. They’re easy on the eyes, easier to care for than a pet or a child, and some are even edible.

Perhaps their most touted virtue is that they help purify the air in your home. But is it true? Follow along as we dig deep to clear the air on houseplants once and for all.

We spend about 90 percent of our time inside, so the quality of our air is pretty important.

Indoor air pollution is caused by fumes released from various sources inside the home, like cigarette smoke, pesticides, cleaning products, house paint, and even our furniture.

Not all of these pollutants are strong enough to smell — VOCs, or volatile organic compounds, are emitted from things like drywall, shampoo, and the plywood your new coffee table is made from.

So, how many plants do you need to purify a room?

You’d need 10 plants per square foot in your home to enjoy any impact on indoor air quality.

Let’s break that down: For a 320 square-foot room, you’d need 3,200 plants for that room alone. Who needs space for a television when you can watch your philodendron grow?

And with the average American home coming out to around 2,300 square feet, that’s 23,330 air purifying plants required to have a measurable effect on air quality. On the bright side, your local florist is going to love you.

Just because houseplants aren’t great at purifying the air in small numbers, that doesn’t mean they’re worthless. Quite the opposite — the human brain loves plants.

Having plants in your home or office can reduce stress, improve concentration, and help reduce depression and anxiety.
